Add posix_time.h from BoringSSL

This is prepares to expose some internal API as OPENSSL_tm_to_posix() and
OPENSSL_posix_to_tm(). They will be used in libtls and ocspcheck(8) to get
rid of the portability nightmare that is timegm().

Also fix the location of OPENSSL_gmtime() and OPENSSL_timegm() (this API
is not yet exposed). The former is from OpenSSL and surprisingly lives in
crypto.h, not asn1.h, and the latter is BoringSSL API and lives in the new
posix_time.h.

Initial diff from beck, this pulls in further upstream work after review
feedback.
